The National Security Agency (NSA) is in the information harvesting business — and business is booming.

That's why the nation's premier covert intelligence gathering organization has been building a million square-foot data mining complex in Bluffdale, Utah, that will house a 100,000 square foot "mission critical data center."

The NSA's official mandate is to listen to and decode all foreign communications of interest to the security of the U.S.

The facility, called the Utah Data Center, is located on Camp Williams, a training facility for the Utah National Guard, is set to open in October.

And boy does it seem like an impressive operation.

One Fox News report says as much as 5 zettabytes — 1 zettabyte = 1 billion terabytes = 1 trillion gigabytes — and with just 1 zettabyte (1024 exabytes) of space, the NSA can store a year's worth of the global Internet traffic (which is estimated reached 966 exabytes per year in 2015).
